Bone fixation methods and devices including adhesive bioactive resorbable bone plates

Abstract

A bone fixation system, device and method are provided herein. A system may include a bone plate. The bone plate is adapted to be affixed to a bone surface, and comprises a bioactive porous portion. The porous portion is adapted to, include bone healing-promoting substances, such as hollow microparticles containing the bone healing-promoting substances embedded in the porous portion. The bone plate father includes at least one attachment portion. In some embodiments, the attachment portion includes a face, which defines indentations, such as dimples, to retain an amount of adhesive.

I claim: 
     
       1. A system comprising:
 a bone plate adapted to be affixed to a bone surface, wherein at least a portion of the bone plate is configured with at least one bioactive portion to incorporate bioactive substances therewith, said at least one bioactive portions being substantially free of adhesive, said bioactive substances including bone healing-promoting substances, the bone plate further comprising at least one attachment portion; and 
 an adhesive adapted to be applied to the at least one attachment portion to affix the bone plate to the bone surface. 
 
     
     
       2. The system of  claim 1 , the at least one bioactive portion further being porous and the bone healing-promoting substances being embedded therein. 
     
     
       3. The system of  claim 2 , wherein the at least one bioactive portion comprises a plurality of hollow microparticles encapsulating the bone healing-promoting substances. 
     
     
       4. The system of  claim 1 , the at least one attachment portion further comprising at least one face defining at least one indentation and configured to retain an amount of adhesive. 
     
     
       5. The system of  claim 1 , the at least one bioactive portion being porous and further comprising a plurality of microspheres, the micro spheres containing the bone healing promoting substances, and the at least one attachment portion further comprising at least one face defining at least one indentation and configured to retain an amount of adhesive. 
     
     
       6. The system of  claim 1 , wherein the bone plate and the adhesive comprises an unblended polymer material. 
     
     
       7. The system of  claim 6 , wherein the unblended polymer comprises a poly lactic acid (PLA) or a PLA-based polymer.
